1992One of the 30 gangsters who was killed in the city during the year. This particular encounter occurred in Lokhandwala, AndheriThis is Singh’s second innings at the city police headquarters. The first was in the early ’90s as Joint Commissioner (crime).

Commissioner Singh says the arrests of judge J.W. Singh — who allegedly was in touch with Shakeel — and film financier Bharat Shah were milestones. ‘‘It became clear that you were in trouble if you were with the underworld, however big you were,’’ says Singh.
